Part 1: Electrical Box Installation & Application Guide

1.1 Applicable Products

1.2 Key Installation Steps

1. Positioning & Marking: Determine the installation position according to construction drawings, mark the fixing points, and ensure the position is flat and free of obstacles.
2. Fixing the Box: Use expansion screws or special fixing clips to secure the box tightly. For concealed installation, keep the box surface flush with the wall; for exposed installation, ensure the box is vertically and horizontally aligned.
3. Wire Arrangement: Put the connected wires into the box neatly, avoid overcrowding, and reserve enough length for later maintenance.
4. Cover Installation: Install the matching box cover tightly to ensure dustproof and waterproof performance (for outdoor/ damp environments).

1.3 Application Scenarios

• Steel Junction Box: Industrial and commercial construction, outdoor electrical projects, high-strength wiring protection
• PVC-U Junction Box: Indoor residential decoration, damp environments, corrosion-resistant occasions
• Switch & Socket Box: Residential, office, hotel electrical renovation
• Meter Socket: Power metering rooms, residential power distribution systems

1.4 Notes

• Do not overload the box with too many wires to avoid overheating
• Outdoor boxes must use waterproof gaskets to prevent water ingress
• Ensure the box is firmly fixed to avoid loosening during long-term use

Part 2: Electrical Conduit & Fittings Installation Guide

2.1 Applicable Products

2.2 Conduit Connection & Installation

1. Cutting & Deburring: Cut the conduit to the required length, remove burrs at the incision to avoid damaging wire insulation.
2. Connector Installation: Use matching adapters or couplings to connect conduits tightly, ensure no gaps between joints.
3. Fixing & Support: Use cable clips or pipe clamps to fix the conduit at intervals of 1-1.5 meters, keep the conduit straight and stable.
4. Bending Treatment: For flexible conduit, bend freely according to the route; for rigid conduit (EMT/GI), use a pipe bender to ensure smooth bending without deformation.

2.3 Fittings Usage Tips

• Fire Safe Cable Clips: Fix cables firmly, choose the right size matching the cable diameter
• PVC Adapter: Used for conduit conversion connection, coat with special glue for tighter sealing
• Electrical Terminals: Crimp tightly with wires, ensure good conductivity and no loose connection

Part 3: Earth Grounding Products Installation & Safety Notes

3.1 Applicable Products

3.2 Ground Rod Installation Steps

1. Drilling & Placement: Drill a hole at the designated grounding position, insert the ground rod vertically, and drive it into the soil completely.
2. Connection Fixing: Use a split bolt connector to connect the grounding wire to the ground rod tightly, ensure no oxidation at the contact point.
3. Soil Backfill: Backfill the hole with fine soil, compact it to enhance the grounding effect.

3.3 Safety & Performance Requirements

• Grounding resistance must meet local electrical safety standards
• All connectors must be corrosion-resistant, avoid poor contact caused by rust
• Solderless connectors: No welding required, crimp firmly to ensure stable current conduction

Part 4: Support Systems Installation Guide

4.1 Applicable Products

4.2 Strut Channel Installation

1. Frame Building: Combine strut channels into a stable support frame according to the load requirements, use connecting accessories to fix joints.
2. Wall/Ceiling Fixing: Use expansion bolts to fix the strut channel frame to the building structure, ensure bearing capacity meets the construction standards.
3. Adjustment & Fixing: Adjust the level and height, then lock all fasteners to prevent displacement.

4.3 Thread Rod & Scaffolding Clamp Usage

• Thread Rod: Used for suspension support, cut to the required length, match with nuts and washers for fixing
• Scaffolding Clamp: Used for construction pipe and scaffolding connection, clamp tightly to ensure construction safety

Part 5: General Safety Precautions & Maintenance Tips

5.1 Safety Rules

• All installation operations must be carried out by professional electricians or construction workers
• Cut off the power supply before installation and maintenance to avoid electric shock
• Use products that meet international and local standards, do not use unqualified accessories

5.2 Daily Maintenance

• Regularly check whether the product is loose, rusted or damaged, replace damaged parts in time
• Clean dust and impurities on the product surface to keep the electrical connection unobstructed
• For outdoor and corrosive environments, regularly check the anti-corrosion performance of the product
